During the last week Chandra completed the observing schedule as
planned.

A real-time procedure was executed on Feb 18 to update the on-board
ephemeris.

A Chandra press release was issued on Feb 23 describing the first
direct evidence for a superfluid at the core of a neutron
star. Chandra observations of Cassiopeia A, a supernova remnant
located about 11,000 light years away from Earth, taken over a decade
show significant cooling in the dense core left behind after the
explosion. This cooling is likely caused by a neutron superfluid
forming in its central regions. For details see:
